BRADLEY A. FISKE, OF NAPERVILLE, ILLINOIS.

PENCIL.

SPECIFICATION forming part of Letters Patent No. 237,005, dated January 25, 1881.

Application filed October 18, 1880. (No model.)

To all whom it may concern:

Be it known that I, BRADLEY A. FIsKE, a citizen of the United States, residing at Naperville,in the county of Du Page and State of Illinois, have invented certain new and useful Improvements in Pencils; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

My invention relates 'to a leadlpencil, simple and cheap of manufacture, efcient in service, and important as a marketable commodity and the novelty consists in the construction and arrangement Vof parts, as will be more fully hereinafter set forth, and specilically pointed out in the claims.

It is a well-understood fact that in articles v of such universal and general use and demand as lead-pencils it is a great desideratum to simplify the construction and reduce the eX- pense of manufacture.

To this end. my invention consists, essentially, in a lead-holder formed, preferably, of wood, and of such size and conformation as to aiiord a convenient handle, and it is provided upon one end with a socket extending longitudinally inward a sufficient distance, approximately' one-half inch, which socket receives the butt of the lead. The socketed end of this lead-holder is adapted to fit snugly within a metal case in such a manner that it will be held suiiiciently firm therein by the friction of the parts, While the other end or .point of said case is beveled or coned, the extreme point being provided with an aperture through which the lead-point emerges. This case may be ornamented in any desirable manner; but to preserve the theory of cheapness I employ the ordinary well-known nickel-plate, and it will be observed that both the conical and cylindrical portions are formed of the same piece of metal.

It will. be seen that the butt of the lead is held firmly in the socket of the lead-holder at one end, while the other end of the lead is similarly held in the point of the metal case.

In case it is desirable to use leads of different sizes, the front end of the lead-holder is beveled or coned sufficiently toleave a proper space for thelongitudinal socket to be formed, and a diametrical slot or kerf is made through the cone in such a manner that the parts may be pressed together so as to embrace the lead firmly. In such construction Iemploy a conical metal thimble, which fits snugly over the severed parts, and being pressed backward forces the said parts together.

If it is desirable to advance the lead with greater precision, and with more gradual regularity than is obtained by the simple friction between the lead-holder and the case, I provide for a sufficient distance, or the entire length of the.leadho1der, the said holder with a quick-screw and the case with a similar conformation, so that the male thread of the holder will correspond with the female thread of the case, and the lead may be advanced or retrieved by turning the holder in the proper direction.

My device will also serve efficiently by forming a slot in the butt of the case and springing in at that point.

In the accompanying drawings, Figure 1 represents a longitudinal perspective view; Fig. 2, a longitudinal elevation, partly in section; Fig. 3,alongitudinal elevation, showing the butt of the case slotted and sprung in upon the holder; Fig. 4, a central longitudinal section, partly in elevation; and Figs. 5 and 6 are enlarged details.

Referring to the drawings, A represents the lead-holder, having a beveled point, a, and a longitudinal socket, a. This socket o is slotted or kerfed diametrically, as shown at a2, to allow the severed parts to be pressed together by means of a conical thimble, a3, and to grasp the lead C firmly at that point.

B represents the cylindrical portion of the case, b the conical portion. and b' the pointaperture through which the lead-point emerges.

D represents the male thread upon the leadholder, d the female thread in the case, and the former is adapted to operate within the latter for the obvious purpose hereinbefore specified.

In Fig. 3, D represents the slot in the butt of the case, which is a modification of this invention.

IOO

I am aware that various devices have been employed to advance and retreat the leads of pencils; but such devices have generally been complicated, expensive, and otherwise not calculated to meet the Wants of the masses.

My pencil is designed to ohviatc the necessity of making wooden lead-pencils at all. It is only necessary to form the case and the stock, which are practically' inexpensive, and then to use the leads. The construction is simple and will last a life time, the only thing necessary to be purchased being,r the leads after one holder and case has been obtained.

I am aware that ordinary wood incased lead-pencils have heretofore been provided with metallic tubular holders which receive the sharpened end when the pencil is to be carried in the pocket, to protect the point of the lead, and reversed when the point is to be used.

I am also aware that an ordinaryY wood-in cased lead-pencil has been inserted in an in ner tube provided with interior pencil-holding projection and with exterior-projecting frictional detents, in combination with an outer protectillg-tube adapted to slide longitudinally thereon.

What I claim as new is- 1. A leadpencil consisting of a lead-holder,

which also serves as a handle, having a cenfo tral longitudinal socket to receive an independent lead-point, a case having a'cylindrical portion, a conical portion, and a lead-point aperture, the holder and handle operating within the case by friction, as shown, as and for the purposes set forth.

2. The lead-holder A, which also serves'as a handle, having a beveled portion, a, and a socket, a', slotted or kerfed, as shown at a,in combination with the case B b b' and an independent lead-point, as and for the purposes set forth.

3. The combination of the lead-holder A, which also serves as a handle, having quickscrew D, conical portion a, socket a', and kerf 45 or slot a2, case li, having conical portion b and aperture b', and having the female thread d and the independent lead, all constructed, arranged, and adapted to serve as and furthe purposes set forth.

In testimony whereof I a'x my signature in presence ot two witnesses.
